HOW TO DETERMINE YOUR CORRECT HELMET SIZE.

1. MEASURE YOUR HEAD. Determine the circumference of the widest part of your head by using a flexible tape measure. Generally, the widest part of a person's head is the area 2.5 cm (1") above the eyes and ears.
However, we suggest measuring at a few points both above and below that line to determine the greatest measurement before referring to our size tables.
We also suggest testing the fit of a helmet one size smaller and one size larger than what the chart recommends. No helmet can provide protection if it's too uncomfortable to wear.

Z1R Helmets - Z1R Nomad Helmet Sinister

Comment: Great fitting helmet. I usually get a size larger than listed and it's always worked...not with this helmet. Stick with the size they suggest. Built well, great design, and light for wearing for long periods of time! NICE BUY!!
